Five students from KG Reddy College of Engineering & Technology submitted an abstract for their mini project on designing a charging circuit for electric vehicles. The proposed charger circuit includes a diode bridge rectifier, interleaved boost DC-DC converter, and single phase DC-AC inverter. An interleaved boost converter is discussed and a single phase DC-AC inverter is modeled and analyzed using different modulation techniques, with sinusoidal PWM chosen. Inductive power transfer technology is used for battery charging. A simulation study was conducted in MATLAB/SIMULINK and a prototype was built to validate the simulation results.

Abstract ABSTRACT:The battery plays a major role in electric vehicle (EV) and for that on-board
battery charger is essential. Therefore, this paper focuses on the design of charging circuit for
EV. The proposed charger circuit comprises of diode bridge rectifier, interleaved boost DC-DC
converter and single phase DC-AC inverter. The design and operation of interleaved boost
converter is discussed. Single phase DC-AC inverter is modeled and analyzed with different
modulation techniques. From the comparison, the sinusoidal PWM (SPWM) is chosen for the
proposed network. Inductive power transfer (IPT) technology is used for the charging of EV
batteries. A simulation study of the proposed charger circuit is carried out in
MATLAB/SIMULINK and a prototype model is built to validate the simulation results.
KEYWORDS: EV, Interleaved boost converter (IBC), IPT and SPWM.
